Summary:

Designed to facilitate analysis of the status of Blacks
around the turn of the century, this oversample of Black-headed
households in the United States was drawn from the 1910 manuscript
census schedules. The sample complements the 1/250 Public Use Sample of
the 1910 census manuscripts collected by Samuel H. Preston at the
University of Pennsylvania: CENSUS OF POPULATION, 1910 [UNITED STATES]:
PUBLIC USE SAMPLE (ICPSR 9166). Part 1, Household Records, contains a
record for each household selected in the sample and supplies variables
describing the location, type, and composition of the households. Part
2, Individual Records, contains a record for each individual residing
in the sampled households and includes information on demographic
characteristics, occupation, literacy, nativity, ethnicity, and
fertility.

Funding

This study was funded by:

United States Department of Health and Human Services. National Institutes of Health. Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD 1-R01-HD18651, and NICHD 1-R01-HD-25856)

Universe:
Manuscript census records for 1910 from counties with at
least 10 percent of the population African-American (Negro, Black, or
Mulatto) located in nine states where a large number of counties had at
least this same proportion of African-Americans (Maryland, Virginia,
North Carolina, Florida, Kentucky, Tennessee, Arkansas, Louisiana, and
Texas). The four states with the largest population of Blacks (South
Carolina, Alabama, Mississippi, and Georgia) were excluded from the
oversample because the 1/250 Public Use Sample (referred to above)
provided sufficient cases for most analyses.

Data Type(s):
census/enumeration data

Data Collection Notes:

The data contain blanks and alphabetic characters. This
oversample can be combined with the 1/250 Public Use Sample by
differential weighting of households (or individuals) by county of
enumeration as described in the User's Guide.

Methodology

Sample:
Sampling was carried out using computer software that
randomly selected households based on the manuscript census microfilm
reel number, sequence, and page and line number, with two different
sampling fractions. Counties in Maryland, Kentucky, and Texas were
sampled using a 0.01 sampling fraction, while a 0.005 sampling fraction
was employed in Virginia, North Carolina, Florida, Tennessee, and
Arkansas. In Louisiana, both fractions were utilized to test optimum
sampling fractions.

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Created variable labels and/or value labels.
